LYMAN L. SHEFFIELD, OF TOLEDO, OHIO.

DENTAL WASTE-COTTON RECEIVER.

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed July 1.1905. Serial No. 267,899.

To all whom, it may concern..-

Be it known thatI, LYMAN L. SHEEFIELD,of Toledo, county of Lucas, and State of Ohio,- have invented certain new and useful Improvements in \Vaste- Cotton Receivers; and I do herebydeclare thatthefollowingisafull,clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form part of this specification.

This invention relates to dentistry, and has particular reference to a wastecotton receiver; and the object of the same is to provide a simple, inexpensive, and sanitary receptacle for the unsightly waste cotton removed from teeth which shall have a normally closed cover to conceal the contents, the cover being opened by the introduction int-o the receptacle of the pliers or other instrument employed to remove the cotton from the teeth and closing automatically the instant the pliers are withdrawn.

In carrying out my invention I employ the novel combination, arrangement, and the details of construction hereinafter shown, described, and claimed.

In the accompanying drawings, illustrative of my invention, Figure l is a side elevation of the complete device. Fig. 2 is a vertical section through the receptacle, the pivoted covers for the same being shown in normally lowered position in full lines and in raised position in dotted lines. Fig. 3 is a plan view of the device, and Fig. 4 is a bottom plan view of one of the pivoted covers.

Referring to the drawings, 1 is a cylindrical receptacle, having the closed bottom 2, the sides being preferably flattened slightly, as at 3 and 4, to facilitate the pivoting of the covers 5 and 6 upon the receptacle. Covers 5 and 6 have the general form of a spherical wedge, and the same are provided with outwardly-projecting pivot-pins 7 and 8, the pins 7 being inserted into perforations spaced apart at one side of the receptacle and the pivot-pins 8 resting in recesses 9 and 10 at the opposite side of the receptacle, the pins 8 being also adapted to enter perforations provided at the upper ends of resilient fingers 11 of a member 12, secured to the side of the receptacle. In this manner the pivoted covers 5 and 6 are made conveniently detachable to permit the removal of the contents of the receptacle, being, however, firmly held against accidental displacement. The covers 5 and 6 are each provided with an outwardly-extend ing flange 13, adapted to normally rest upon the top edge of the receptacle, and the inner portions thereof within their pivotal axes are inclined, as at 14., the lower edges of said inclined portions being adjacent to each other.

The operation of the device is plainly shown in Fig. 2. The pliers 15, carrying the cotton, are introduced into the receptacle, the same thereby coming into contact with the inclined portions 14. of the covers, which by reason of such contact will be elevated to the position.

(6. However, the instant the cotton has entered the receptacle a sufficient distance, as at b, the covers, owing to the greater weight of their outer ends, will resume their original position. When the pliers are now withdrawn, the cotton will be removed by contact with the lower margins of the inclined portions of the covers, being then deposited in the receptacle. In the same manner the cotton from a smooth broach may be removed and deposited in the receptacle.

In constructing my invention the parts thereof are preferably made of metal, and since the pivoted covers are readily detachable the device is convenient to clean, being especially constructed to permit thorough sterilizing.

The pivoted covers for the receptacle having the general shape of a spherical wedge, the contents of the receptacle will be concealed when the covers are elevated.

The novelty, utility, and advantages of my invention will be apparent.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a waste-cotton receiver, a cylindrical receptacle, and two spherical wedge-shaped members pivoted upon said receptacle and weighted at their outer ends to normally close the same, substantially as described.

2. In a waste-cotton receiver, a cylindrical receptacle, and two spherical Wedge-shaped members pivoted upon said receptacle and detachable therefrom, substantially as described.

3. In a waste-cotton receiver, a receptacle, and two spherical wedgeshaped members pivoted thereon, having their adjacent portions inclined, substantially as described.

4. In a waste-cotton receiver, a receptacle, and two cover-sections pivoted to the sides of said receptacle, said sections having their inner portions inclined to cause them to he myownlaifix mysignatuiein preseneeo'f two ralseil when said inclined portlons are enwltnesses. gagged, and having their outer portions Weight- I LYMAN L.
